Known as the “Grand Condé”, the Pink Diamond is a historic gemstone weighing more than 9 carats, documented in the collections of the Princes of Condé since the 18th century. This jewel, exceptional in both color and provenance, was stolen in October 1926 before being recovered shortly afterwards, hidden inside an apple. 

A century later, the Pink Diamond is once again on public display at this special exhibition. To mark the occasion, the Musée Condé and L’ÉCOLE, School of Jewelry Arts have undertaken an extensive interdisciplinary research project, the first of its kind for a diamond of this calibre. Major gemmological and historical analyses are now revealing all its secrets. 

The exhibition was designed by Mathieu Deldicque, chief heritage curator and director of the Musée Condé and the Living Museum of the Horse at the Château de Chantilly and by Marie-Laure Cassius-Duranton, art historian and gemmologist at L’ÉCOLE, School of Jewelry Arts.
